Fig. 5From: Phylogeographical and population genetics of Polyspora sweet in China provides insights into its phylogenetic evolution and subtropical dispersalHaplotype geographical distribution and interspecies network of combined cpDNA (trnH-psbA, rpoB-trnC, and petN-psbM) in 32 populations of Polyspora. (a) Haplotype map; (b) Interspecies haplotype network. Size of the circle is proportional to the relative frequency of the haplotype. The map was drawn by the authors using the popart-1.7 software (http://popart.otago.ac.nz/), and the base map was the software’s built-in mapBack to article page
